Storm level needed
Nyborg sits at 55.31N 10.79E in South Denmark, Denmark. The IGRF-14 centered dipole puts Nyborg at 55.3 degrees geomagnetic latitude, 0.0 degrees farther from the magnetic pole than its map latitude suggests. Nyborg sits at 55.3 degrees geomagnetic. By SWPC's rule the average oval edge is overhead at Kp 6, and aurora is usually visible on the northern horizon at G1 (Kp 5) or less.
"aurora is commonly visible at high latitudes (northern Michigan and Maine)"
The nearest other Glow towns are Odense (27 km), Svendborg (30 km), Slagelse (37 km). Odense sits 0.1 degrees higher on the dipole and needs the same Kp.
Approximate: SWPC calls its Kp to latitude rule an average, and a centered dipole can differ by a degree from fuller field models. How the storm level is matched
The year in darkness
Every night of 2026 at Nyborg has some civil darkness; the shortest month sample still has 4.4 hours. Every evening of the year at Nyborg clears Glow's dark-season bar of 4 hours of civil night between 18:00 and 06:00. Nyborg's longest night of the year, Dec 18, has 15 h 14 min of civil night.
Solar midnight at Nyborg, when the sun is lowest, falls at 00:12 on local clocks on December 15 and 01:17 on June 15. That is 12 min after midnight in December and 1 h 17 min after midnight in June, the gap set by daylight saving and the equation of time. So at Nyborg the darkest hour sits near the middle of SWPC's 10 PM to 2 AM window in winter.

By the 15th-of-the-month sample, December is the darkest month at Nyborg with 15.2 hours of civil night and June the lightest at 4.4. Across the year Nyborg gets 3,684 hours of civil night. Astronomical night at Nyborg, the sun 18 degrees or more below the horizon, lasts 12.1 hours on December 15.
NASA POWER's 2001 to 2020 all-hours climatology puts mean cloud amount for the 1 degree cell around Nyborg at 68% across the year, from 57% in April to 80% in January. In the months with at least 4 hours of civil night Nyborg averages 68%, against a median of 70% for Glow towns in Denmark.
Multiplying civil night by the clear share of the sky gives October the best score, 3.9 hours, ahead of September at 3.8. Nyborg's equinox months score 3.5 in March and 3.8 in September, the weeks SWPC links with larger storms.
Kp history
From 1996 to 2025, the GFZ Potsdam record shows a 3-hour Kp of 6 or more, the level that puts the average oval edge over Nyborg, on 3% of days. At Nyborg's level the share runs from 1% in December to 5% in October, while storm days with Kp 5 or more made up 10%.

Moon, next 30 nights
Over the 30 nights from Oct 2, the new moon falls on Oct 10 and the full moon on Oct 26, in Europe/Copenhagen dates. 15 of the 30 nights at Nyborg have at least 2 moon-free dark hours inside 10 PM to 2 AM, and Oct 6 has the most at 4 h. Tonight Nyborg has 11 h 13 min of civil night, 1 h 46 min of it with the moon down.
